Title: Optical disk recorder
Inventor: OGAWA KOUICHI
IPC: G11B7/004
Filed: 1979-11-22
Abstract: PURPOSE: To eliminate virtually the time delay in the reading, by dividing the area on the optical disk into about 1,000sec and then securing the recording of the track number on each sector.  
     CONSTITUTION: A piling is secured through piling part 14 between the FM-modulated record information signal 9 and the track number repeat signal 10 having the frequency component lower enough than the signal 9. These piled signals are then turned into the pulse signal 12 through pulse forming circuit 15, and then the laser beam is modulated by the optical modulator 16 to be recorded by the writing head 17 and in the form of the bit 13. At the same time, the electric signal during the reading is supplied to the demodulator 24 via the low-pass filter 22, and the track number information is detected in about 1,000 times during a turn of the disk along with demodulation of the record information signal through the demodulator 25. As a result, the time delay can be virtually eliminated when one is selected among  about 50 tracks which are decided most by a mechanical means when the positioning is given to the tracks.

Title: Semiconductor integrated circuit
Inventor: ONO YOSHITERU
IPC: G06F1/06
Filed: 1989-06-14
Abstract: PURPOSE:To reduce the waste of operating speed by feeding back the output signal of an internal reference signal generation circuit in an asynchronous type memory to an input side. CONSTITUTION:When skew occurs in input signals A, B and C such as an address signal, a chip select signal, etc., the rise/fall of the output of the internal reference signal generation circuit is fed back to the input side via a delay circuit 2 with a level change detection signal from the level change detection circuit 1 for a signal changing first. The level change detection signal from the input signal having negligible inter-signal skew can be neglected by feedback to the circuit 2, and the fall of the output signal of the internal reference signal generation circuit can be performed. Therefore, the operation of a memory can be started from the trailing edge of the output signal from the internal reference signal generation circuit, which accelerates the operating speed.

Title: Intermittent reception processing method for mobile station
Inventor: SATO KAZUYOSHI
IPC: H04W52/02
Filed: 1992-06-11
Abstract: PURPOSE:To recognize an other side party at a call loss and to save a time loss till a succeeding incoming call by storing a caller dial number and a mobile station causing a call loss by a base station, informing the mobile station at a succeeding slot allocated to the mobile station of them and allowing the mobile station to revise a period of an intermittent slot to that having a shorter period. CONSTITUTION:When outgoing incoming call processing is absent for a long time, a mobile station increases an interval between ON and OFF of a received power and finally the intermittent period reaches the maximum and constant interval. When outgoing incoming call processing is implemented, a mobile station decreases the interval of intermittent for each event of outgoing incoming processing. Finally the intermittent period is minimized and becomes a prescribed interval. Even when a call is sent from a base station and a call loss takes place because of the long intermittent period of the mobile station, the base station includes call loss information in a notice signal and sends the resulting information to the mobile station. The mobile station references to the information in the notice signal to implement the outgoing incoming call processing and decreases the intermittent period to prepare for the succeeding incoming call.

Abstract: PURPOSE:To prevent a wind-clamping phenomenon and a nonuniform annealing and to secure the low iron loss characteristics by a method wherein the wound core is constituted of plural core blocks divided in the laminated direction of amorphous magnetic alloy thin belts and respectively wound up in the prescribed shape and are respectively annealed. CONSTITUTION:Core blocks 3a-3c, which are respectively formed by winding amorphous magnetic alloys and are respectively formed in the configuration of a curve at the four corners thereof and in the configuration of a straight-line at the other parts, are separately formed and after an annealing is performed on each core block, the core blocks are assembled and the amorphous magnetic alloy wound core is constituted. Hereby the wound core is formed in a configuration that the core blocks mutually adhere at the straight-line parts thereof and cavities 7 exist at the four corners thereof. As a result, a wind-clamping phenomenon at the four corner parts of the wound core is prevented and a reduction in the magnetism characteristics of the amorphous alloy thin belts, which is caused by an excessive stress, is eliminated. Furthermore, as an annealing is performed on each core block 3a-3c, there is no overannealing and underannealing on account of a nonuniformity of the temperature distribution. Accordingly a drop of the characteristics of the thin belts is eliminated. Moreover, an assemble, support, cooling and so forth of the core can be executed utilizing the cavities 7 located at the four corners thereof.
